"There's no restaurant to go to, so you have to actually follow the truck around and figure out where it's going to be," said a truck patron.

It's a mix of technology and the iconic LA taco truck, and a blend of cultures. Kogi serves Korean-style barbecue in tortillas.

"I've been following the Kogi barbecue for like two or three months on Twitter, and I just happened to look and my head popped off because they were coming to Melrose," said a woman at the truck on a recent night.
